Tilt the upper case about 45 degrees so that the keycap letters are upside-down.

Place the top edge of the upper case on your work surface as close to the lower case as possible.

Hold the upper case at about 45 degrees to avoid straining the interconnect cable.

Remove the black tape covering the interconnect cable connector.

Use the pointed end of a spudger to push the interconnect cable connector's locking tab toward the cable.

Use a pair of blunt tweezers to grip the interconnect cable by the blue section close to the connector.

Pull the interconnect cable out of its connector in the direction of the cable.

Make sure the locking tab is in the unlocked position.

Remove the upper case from the lower case.

Apply a few drops of high-concentration (90% or higher) isopropyl alcohol under the battery edge opposite the battery connector.

Slowly insert the tip of an opening pick under the top edge of the battery.

Push about half of the opening pick under the battery while slowly lifting up.

Use your fingers to lift the battery about 1 cm above the battery recess.

Rotate the battery 45 degrees so that the edge closest to the battery connector rests in the battery recess about 1 cm from the connector.

Place two fingers under the bottom side of the battery to support it.

While supporting the battery, disconnect the battery by pulling on the three cables as close to the connector as possible.

Remove the battery from the keyboard.

If there's any alcohol solution remaining in the keyboard, carefully wipe it off with a coffee filter or allow it to air dry before installing your battery.
